Answer 2

@using (Html.BeginForm("SaveReceipt", "ClinicInvoiceReceipt", FormMethod.Post, new { id = "form1" }))
{ 
    <p>main page form </p>
    <input type="button" id="ShowConfirmDiv" value="Submit" />
}

<div id="ConfirmationDiv">
    <p>Are you sure you want to submit this form?</p>
    <input type="button" id="ReceiptSave" value="Ok"/>
</div>

<script type="text/javascript">
    $(document).ready(function () {

        $("#ConfirmationDiv").dialog({
            autoOpen: false,
        });

        $("#ShowConfirmDiv").click(function () {
            $("#ConfirmationDiv").dialog("open");
        });

        $("#ReceiptSave").click(function (e) {
            e.preventDefault();
            $('#ConfirmationDiv').dialog('close'); // for closing popup
            $("#form1").submit();
        });
    });
</script>
